Jazz plugin is a "msi package" it's the same problem, i have the message "JazzControl.dll failed to register" (even with chrome installed)

"Here's some other considerations: ..."Be sure I tried all of this with a clean machine, and with another one too.

"Make sure that your OS is behaving correctly with MIDI" I'm sure, I never had a midi problem. and I don't think it's a midi problem.For the Code editor I think it's Java or quicktime (two softwares I don't like ...)For the Jazz plugin I don't know.

when I go to editor page, (when the midi in/out section is yellow and prompt) the device selected is the Code (usb) (it's the first on the list)I can't select this one but I can select the others ... but just when it's yellow, after I can select the Code It's the same on Firefox or Chrome

I found a way to install the jazz plugin (1.2) without error messageI had to install the visual c++ library (2008)but it still doesn't work (firefox & chrome)

The only change is: I see the midi in/out selector in firefox now, but not the devicesI see my "nanokorg" inside (a very cheap 40$ master keyboard but supplied with a driver .......) but that's all (in firefox)

After spending some time on Lapin's computer, it seems the issue is related to windows XP and the French language. Windows XP doesn't properly pass the port name. It lists it as "P riph rique Audio USB" - for whatever reason, XP is unable to pass the "é" character. As a result, any attempt to use this name to open a MIDI port results in failure.

This is just an educated guess, however, and I'm unable to confirm with my own install of XP. Can anyone confirm this?

That's not all, I made a "driver" (not really a driver but now the Code is recognised by the Code ID)because the first solution doesn't solve the conflict problem between the code and others no named devices, just change the name of the generic devices

so I edited a second time the C:\windows\inf\wdma_usb.inf

add this line in [Manufacturer] section:%Livid.Mfg%=Livid.Section

add this two lines in [Strings] section: (end of the file)Livid.Mfg="Livid"USB\Vid_04D8&PID_FB3C&MI_00.DeviceDesc="Livid Code"

add all of this:[Livid.Section]%USB\Vid_04D8&PID_FB3C&MI_00.DeviceDesc%=USBMIDI.Livid,USB\Vid_04D8&PID_FB3C&MI_00
